Pisa is so tiny that you can't really have a bad location. It was right beside the train station which is easy and it was super clean with a nice atmosphere. Not sure I would recommend staying in Pisa just because there isn't very much to do other than check out the tower/walk around but if you do need to stay overnight then is is the hostel for you. Only critique I have is that the walls are VERY thin. Heard the shrieking kids next door all day and night. If you're not next to kids youre good

Really close to the town centre. I spent three nights here, exploring Pisa for a day and then using the hostel as a base to visit the beach (20 minute bus away) and cinque terre (slightly over an hour away on the train). The train station is a 5 minute walk away and the airport is about 15 minute walk away. Great location, friendly staff and reasonably priced food and drink - would recommend!
